3. Connection
The control panel is connected to the air handling unit via an RJ10 (4P4C) cable.
The maximum cable length should not go above 50 meters or it will not work.
Up to five SAVE LIGHT control panels can be connected to one air handling unit. When con-
necting multiple control panels, the HMI Address has to be adjusted. The addresses HMI6 to
HMI10 are intended for SAVE LIGHT; no address should be assigned twice. From Factory the
SAVE LIGHT is assigned to the address HMI10.
A 12m connection cable and a Y-adapter for connecting several control units can be found in
